Well I have some information that may help out here. I am going to try this when I get my truck up and running again. I have a friend that I used to work with about two years ago that has a 1993 Gen 1. I spoke to him a few weeks ago to verify this information. He has a set of MAC 1 5/8" long tube headers for a 1993 MUSTANG GT on his truck. I have seen them personally. He still had the midship tank installed and here is what he did. For the driver side he had the collector area either bent or cut and a curve installed to point it towards the passenger side. For those of us not running a mid-ship tank this won't even be an issue. For the pass side he said it was a no problem drop in fit. Matched up to the cylinder head no problemo. I don't know what he use for exhaust from the headers back but I guess the rest can be configured to the owners liking/engine combo. I recommend and will definitely be using an "X". So this really makes me wonder. If the MAC 1 5/8" er's fit well what about the 1 7/8" from like Bassani or some other manufacturer? Or do they have to be MAC? Can it be 1 5/8" long tubes from some other manufacturer. We all know how much some of the Gen 1 specific long tubes can go for. Ever priced a custom set ?? Can you say "cha ching". Try like $1000 + by the time its all said and done. Granted they are totally awesome pieces of work. But my wallet just cant take that kind of hit. Heck you can get a ceramic coated set of used MACs for like $250-300 I think. Well maybe this will give some of us an alternative for better performance. Our fellow friend Hotrod is running some 1 1/2" Headmans with some pretty darn good results. Cant say I really know of any other Gen 1 running 13.2 naturally aspirated. Must be in the tune and the exhaust. So thats the info. Lets see what happens.
